Challenge: Print Tree Nodes within a Range

Let’s print nodes within a certain range in a BST.

We'll cover the following

Problem#

Print only those nodes of the tree whose value is in the given range.

Input#

Two node values.

Output#

An in-order list of the node values.

Sample input#

min = 3
max = 9

Sample output#

3 4 5 6 7 8 9

Let’s look at the illustration below to better understand the problem.

PrintDataInRange(3, 9) = 3 4 5 6 7 8 9
